Vapor Barrier for Insulation

I have a building that is currently not heated or insulated. It's open up above all the way to the rafters. Besides the walls - I plan on putting drywall on the "ceiling" overlays - then insulating the "attic". Currently the ceiling is covered with heavy plastic sheathing. Can I leave this up there and put the drywall over the top? The plastic would then be a vapor barrier for the loose fill insulation or unfaced fiberglass. Would this work ??? Am I on track with this ??

Yes, you can leave the plastic up and cover it with sheet rock. But before you do, do all your mechanicals first, electrical, plumbing and/or heating/cooling. Also tape all the seams and any penetrations you might make in the plastic before installing the sheet rock. Then you can either use loose fill or unfaced insulation above the plastic.
